United States Patent O 4 Claims ABSTRACT F THE DISCLOSURE A hinge Iassembly having upper and lower flanges for attachment to a door or window sash and .trarne respectively. A sleeve is provided on each flange for coaxial alignment and a tubular spindle is positioned in such sleeves for rotation. A screw bolt traverses the spindle and a flange on one end 'bears against the spindles lower end. The bolt passes through a 'bushing bearing against the upper end of the spindle and a nut and lock nut threadedly engage the free end of the bolt for enabling the "bushing, screw bolt and spindle to be removed from the sleeves so that the flanges can remain `attached to the sash and frame.

The present invention relates to a cramp iron, hinge or ride for doors, windows, vehicle 'bodywork or coachwork in particular.

The so-called wings or sashes of doors and windows have hitherto been mounted by means of straight hinges, so-'called spade or analogous joints, angle hinges, butt hinges, or joint frames or hinges. The three rst mentioned, as well as modified forms thereof, can be considered only for quite simple doors and windows, and are unsuitable in cases in which greater demand-s must be met, specifically in bodywork or coachwork for Vehicles. The known butt hinges and joint frames or hinges are objectionable in that they are stiff when their movable flange rests on the hinge bolt in a close t, and are subject to rapid wear if such ilange is mounted on the hinge bolt with a degree of play. In order to remove a door, Window wing or panel, it is necessary to unscrew a ange of each hinge, and an accurate repositioning thereof is extremely diicult.

The present hinge comprises a lower flange portion having a sleeve for fastening to the door frame or window frame, and an analogous upper flange portion for fastening to the so-called Wing or sash of the door or window, and is characterized in that between the coaxially arranged sleeves 0f the upper and lower ilange portions arranged in abutting relationship is positioned, a tubular spindle against the lower end of which bears a head ilange of a screw 'bolt traversing the tubular spindle, and against the upper end of which bears a ilange of a bushing or the like. The 'bushing engages in the tubular spindle and is traversed by the screw bolt, and with the flange thereof 'being held in vcontact with the tubular spindle by a nut screwed onto the thread of the screw bolt projecting above the bushing, and secured by a locknut.

A hinge lof this type is characterized by an easy action and very little wear even after extended use, and by virtue thereof it is possible to remove a door or window without unscrewing one of its flanges, after unscrewing the nut and withdrawing the screw bolt, and to ret the door or window in precisely the same position thereafter. It is thus especially adapted to fulfill the requirements prevalent in vehicle body-building, in particular.

The invention will be described hereinafter in particular, in respect of an embodiment of a cramp iron, hinge or ride for doors or windows, for vehicle bodywork or coachwork in particular, with reference being had 3,421,177 Patented Jan. 14, 1969 ICS to the accompanying drawings, with the description and drawings 'being given by way of example but by nO manner of means of limitation.

FIGURE l is an elevational view of a hinge according to the invention in the unfolded position,

FIGURE 2 is a longitudinal sectional view taken through the hinge shown in FIGURE 1,

FIGURE 3 is a top plan view of the hin-ge, and

FIGURE 4 is an exploded view of the components of the hinge according to the invention.

The hinge as illustrated comprises two rigid flanges 1 and 2 provided with screw holes 1a and 2a respectively. On the rim or edge areas of the flanges, which face each other, and integral therewith, are sleeves 1b and 2b respectively. The length of each sleeve is equal to half the height of each flange, with the tlange 1 Iand sleeve 1b constituting the lower part of the hinge, and the flange 2 and sleeve 2b the upper part of the hinge. The Vsleeves 1b and 2b appropriately are defined by thickwalled pipe sections which are secured to the rim areas of the corresponding anges 1 and 2 by seam welding. The sleeves m-ay, however, also be formed by appropriate rolling of a projecting part of the correct height lof the corresponding flanges 1 and 2. The flange 1 is intended to be fastened in or on a door frame or window frame, while the flange 2 is intended to be secured to the door or window wing or sash in the same manner. A hollow spindle 3 of thickwalled pipe section is inserted into the adjacent and aligned sleeves 1b and 2b so as to allow rotation. A screw :bolt 5 traverses the hollow spindle 3, with its head 4 fitting into the lower extremity of the spindle, and having a ilange 4a which bears on the lower end of the sleeve 1b. In order to save material and machining costs, the screw bolt 5, the head 4, and the ilange 4a are not made from one piece, 'but the screw bolt 5 is welded into an axial bore of the head 4. Onto the threaded portion of the screw bolt 5 is positioned a bushing 6 which engages in the hollow spindle 3. A ilange 6a on the bushing bears against the upper extremity of the spindle 3, and the upper extremity projects by a small fraction of an inch above the top end of the sleeve 2b of the ilange 2. Above the bushing 6, and ange 6a, a nut 7 is screwed onto the threaded portion of the screw bolt 5 and is secured by means of a lock nut such as a cap nut or the like 8.

The top edge of the sleeve 1b of the tlange 1 may have its inner side provided with a continuous lubricating groove 1c, and the top edge of the sleeve 2b may have a continuous lubricating groove 2c. A hole 6b for grease is formed in the flange 6a of the bushing 6 as shown in FIGURE 2. Lubricating oil which is introduced into the hole 6b, is received by the groove 2c and is distributed peripherally. The oil seepinlg between the spindle 3 and the sleeve 2b of the ilange 2 reaches the lubricating groove 1c of the sleeve 1b and thereupon lubricates the entire surface of the spindle 3 situated within the sleeve 1b. Hence, extended satisfactory lubrication of the spindle 3 is assured, since a certain reserve of oil remains in the lubricating grooves 2c and 1c for some time.

The nut 7, which is secured by the lock nut 8, ilrmly holds together the head 4, and the flange 4a of the screw bolt 5, the Abushing 6, and flange 6a, and the hollow spindle 3 located 'between the ilanges 4a and 6a respectively. This assembly as a whole may be rotated within the sleeves 1b and 2b of the flanges 1l and 2. 'Ihe door or window mounted on the ilange 2 may be moved very easily due to satisfactory lubrication. Since the spindle 3 is also entraiued a little by the sleeve 2b of the flange 2 during each displacement of the door or window, the spindle 3 is not always stressed at the same point, 'but at a dilerent point of its bearing surface during each displacement, so that it suffers extremely little wear.

It is an essential advant-age of this door `or window hin-ge that the door or window wing or sash secured by means of the same may be removed without freeing either of the flanges 1 and 2, and may be reiitted in precisely the same position. To this end, the lock nut 8 and the nut 7 are simply unscrewed from the screw bolt 5, and the `bushing 6 withdrawn from the spindle 3, whereupon the screw bolt 5 together with the spindle 3 is withdrawn downwardly from the sleeve 2b of the flange 2 remaining fastened to the door or window, and from the sleeve 1b of the ange 1 remaining fastened to the door or window frame, so that the door or window may be removed.

The tubular sections required to produce the sleeves 1b and 2b, as well as the spindle 3, are available in finished form in the trade, and need merely be cut to appropriate length and provided with the lubricating grooves 1c and 2c.

If desired, the Ibushing 6 may 'be formed with a screw thread and may be screwed into a corresponding inner screw thread provided in the upper extremity of the spindle 3. In this case, two or more radially directed lblind holes 6c are formed in the ange 6a, which serve for receiving a pin for tightening the Ibushing 6.

As shown by the dash-dotted lines in FIGURES l and 2, a special bracket 9 may be incorporated, which is provided with screw holes 9a, if the doors or windows to be hung are particularly heavy. The 'bracket 9 has a lower portion 9b which is bent at right angles and formed with a hole for the screw 'bolt 5, which is clamped between the ilange 6a and the nut 7. The support bracket 9 projecting above the door or window hinge is screwed to the door or window frame hy means of screws and substantially relieves the flange 1 of load, with this flange being screwed to the door or window frame as well. Unless a support 'bracket 9 of this type is incorporated, the nut 7 bears directly on the flange 6a, instead of on the bent portion 9b as shown in FIGURES 1 and 2.
